This repo is to create rancher and add kind (Kubernetes IN Docker) into Rancher automatically with all-in-one script. It also installs cluster monitoring, linkerd and linkerd-viz

• Create Rancher UI
• Create Kind Kubernetes cluster
• Init rancher admin’s password
• Update server url in rancher
• Import kind cluster into rancher
• Install cluster monitoring
• Generate linkerd certificates
• Install linkerd
• Install linkerd-viz

Rancher API keeps changing, currently we hard code the rancher version to version "v2.6.2"

1. Make sure you have installed:

• Kind (kubernetes in docker) locally. The installation instruction is here: https://kind.sigs.k8s.io/docs/user/quick-start/
• Kubectl
• Linkerd cli
• Helm 3

2. Adjust docker engine memory

Default docker engine is set to use 2GB runtime memory, adjust it to 8GB+ if you can.

3. review kind.yaml

Currently I only set one worker node, you can add more if you need.

$ ./rkind.sh create

$ ./rkind.sh destroy

If you'd like to change the kind configuration, please update file kind.yaml. For details, go through https://kind.sigs.k8s.io/

The helm charts includes the original charts as dependencies, adds overrides, and might add extra dependencies, like adding loki to grafana and a nodeport service to linkerd-viz.

• Extra dependencies (loki + promtail): https://github.com/presidenten/rancher-in-kind/blob/master/charts/monitoring/Chart.yaml#L8-L16

• Value overrides: https://github.com/presidenten/rancher-in-kind/blob/master/charts/monitoring/values.yaml

• Helm value overrides: https://github.com/presidenten/rancher-in-kind/blob/master/charts/linkerd-viz/values.yaml

• Extra nodeport service: https://github.com/presidenten/rancher-in-kind/blob/master/charts/linkerd-viz/templates/services/linkerd-viz-nodeport.yaml
